Stuck in an infinate loop

Question

try
     URL temp = new URL(urls);
     BufferedReader bufRed = new BufferedReader(new InputStreamReader(temp.openStream()));
     String stringBuf = "";
     while(!stringBuf.equals(null))
          stringBuf = bufRed.readLine();
          StringTokenizer tok = new StringTokenizer(stringBuf, " ");
          while(tok.hasMoreTokens())
               if(tok.equals(request.getParameter("keyword")))
                    out.println("Found the word(s) "+request.getParameter("keyword")+" in the URL: "+urls[i]);
     bufRed.close();
     }catch(IOException ioe){}
It gets stuck on the while(tok.hasMoreTokens()) loop for ever, does anyone have any ideas to why this is happerning?
Many thanks for any help :)

Thanks for that, it seems to have stopped it from looping, although incorrect output is produced.
try
     URL temp = new URL(urls);
     BufferedReader bufRed = new BufferedReader(new InputStreamReader(temp.openStream()));
     String stringBuf = "";
     while(!stringBuf.equals(null))
          stringBuf = bufRed.readLine();
          StringTokenizer tok = new StringTokenizer(stringBuf, " ");
          while(tok.hasMoreTokens())
               if (tok.nextToken().equals(request.getParameter("keyword")))
                    //if(tok.equals(request.getParameter("keyword")))
                    out.println("Found the word(s) "+request.getParameter("keyword")+" in the URL: "+urls[i]);
          tok.nextToken();
     bufRed.close();
     }catch(IOException ioe){}
If the keyword is for example 'Mez' and the URL is http://www.astonlms.co.uk, shouldn't that print that it has found that keyword in the page its looking at?
